Doors of 55", just reaching 48" behind the bumper (legal). They can adjust the second break angle. Or just stay at 11 deg. I am hoping to tuft test and maintain attachment at 16 or 18 deg. This is to follow Aeroheads advice that drag is porportional to wake size, or as I call it, the 'aperture'.
Once I succeed on the basic tail I will put tail lights at the tips and add a foldable or detachable polycarbonate extension to ~96".
I think you will start to see results with a new 11 degree angle at the vehicle. I like that your design allows for multiple angles for your main panels. I expect you will see separation at 18, 16, and 14 degrees but it doesn't hurt to try if you have the time.

(You will save me the time on my similar project too )
